PUMPING MECHANISNI.

SPECIFICATION forming part of Letters Patent No. 792,839, dated June 20, 1905.

Application iled March 21, 1905. Serial No. 251,276.

To 1r/ZZ whom it may concern.'

Beit known that we, JOEL O. NEATHERY and J ou M. ADAMS, citizens of the United States, residing at Arkadelphia, in the county of Clark, State of Arkansas, have invented certain new and useful Improvements in Pumping Mechanism; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to pumping systems, and more particularly to pumping systems for railroads, and has for its object to provide a system by means of which water may be pumped to a reservoir automatically, the mechanism being oper-ated by the rolling-stock passing over the, track.

Another object is to provide a mechanism which will be simple in arrangement and which will be so constructed that the danger of break-A age or derangement of the parts will be reduced to a minimum.

Other objects and advantages will be apparent from the following description, and it will be understood that modifications of the specific construction shown may be made and any suitable materials may be used without departing from the spirit of the invention.

In the drawings forming a portion of the specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is an elevation of the present invention, showing the pump' proper disposed in a stream. Fig. 2 is a section on line 2 2 of Fig. 1, showing the construction of power mechanism. Fig. 8 is a top plan view. Fig. 4 is a sectional view of the pump.

Referring now to the drawings, there is shown a bridge 5, which spans a stream of water, and mounted upon the bridge in the usual manner there are railroad-rails 6 and 7.

The present invention consists of a hollow body 8, having the form of a shallow rectangular tank, which in the present instance is secured beneath the bridge and opens through the surface of the latter. Disposed within the body portion 8 there is a vertically-movable member 9, which has the same general form of the body portion, but which is inverted, the

open side of the member 9 beingdirected downwardly. As shown, this member includes side walls 10 and a top 11, and the walls lit the walls of the body portion 8 snugly, so that passage of iuid from the space within the inclosure of the member 9 and the body portion is prevented. Helical springs 1Q are disposed within this inclosure bearing at one end against the under face of the top 11 and at the other end against the bottom of the body portion, these springs being thus arranged to hold the member yieldably at the upward limit of its movement. Each of the rails 6 and 7 includes a central portion 13 and end portions 14, the central portions being hinged at their ends to the adjacent ends of the end portions, and the portions 13 are secured to ties 15, which are mounted upon the upper face of the top 11 of the member 9.

Communicating with the body portion 8 at the center of its bottom there is a pipe 16, which extends downwardly and which communicates at its lower end with a horizontallyextending cylinder 17, adjacent to one end of the latter. Disposed within the cylinder there is a piston 18, to which there is secured a piston-rod 19. The piston lies within the cylinder beyond the pipe 16, the piston-rod eX- tending beneath this pipe and passing out through an opening Q0 in the end of the cylinder which lies adjacent to the pipe 16, this opening 20 being provided with a suitable packing-gland 21.

A pump 22 is provided, which consists ofv a cylinder 23, open at its upper end and having a down wardly-directed funnel-shape partition 24 therewithin between its ends. The partition has an inlet-opening 25 therein provided with an inwardly-opening valve 26, and connected with the partition at its center there vis a discharge-pipe 27, which communicates with an opening 28, formed through the partition and which is curved outwardly and upwardly, passing out through a slot 29 in the side of the cylinder below the partition. Slidably disposed within the cylinder above the partition there is a piston 30, having an upwardly-extending wall 31, and extending upwardly from the piston centrally thereof there is a rod 32, to which there is removably IOO secured a cable 33. A plurality of weights 34: are provided, which are circular in shape and each of which is provided with a. central opening 35, and these weights are engaged with the rod 32 and lie within the inclosure of the wall 31 and upon the piston 30, the number of weights being varied to suit different conditions.

Extending upwardly from the cylinder 23 there are a pair of convergent arms 36, which are connected at their upper ends by a horizontal portion 37, and depending from the horizontal portion there is a pulley 38, with which the cable 33 is engaged, and beyond this pulley the cable is connected with the piston-rod 19;

A suitable fluid is contained within the body portion 8, the cylinder 17, andthe pipev 16, and it will be apparent that when a pieceA of rolling-stock passes over the rail-sections 13 the member 9 will be depressed, which will force the fluid-into the cylinder 17, thus moving the piston 18 and raising the piston 3() to draw water into the cylinder 23 above the partition 24, it being understood that the pump is disposed in asuitable water-supply. The opening 28 is provided with a downwardly-opening valve 39, and it willbe apparent' that when the weight of the rollingstock has left the rail-sections 13 the weights 34 will return the piston 3() to its original position, thus forcing the water out through the pipe Q7 into a tank 4:0, into which it is a-rranged to discharge.

What is claimed is- 1. A pumping system comprising a hollow body portion open at its top, a vertically-movable member disposed within the body portion, vertically-movable rail-sections carried by the member, said body portion being adapted-for the reception of a fluid, a cylinder having a closed end, a piston slidably disposed in the cylinder, connections between the eylinder and the body portion for the passage of liuidy from the body portion to the cylinder, said connections communicating with the cylinder between its closed end and the piston, a pump, and connections between the pump and the piston for operation of the pump when the piston is moved.

2. A pumping system comprising a hollow body portion, a member slidably mounted in the body portion, means for holding the member yieldably at one limit of its movement,

movable rail-sections connected with the member and arranged to receive rolling stock thereupon, saidy rail-sections being arranged for movement under the weight of the rollingstock to move the member against the action of the holding means, a cylinder, a piston slidably disposed wthin the cylinder, said cylinder having a closed end, a pipe communicating with the body portion and with the cylinder between the closed end of the latter and the piston', said body portion, piston and pipe being adapted for the reception of iiuid, said member being adapted to force iiuid from the body portion through the pipe to the cylinder when the member is moved against the action of its holding means, and a pump connected with the piston for operation when the piston is moved.

3. In a pumping system, the combination with a hollow' body portion, of a member disposed within the body portion for sliding movement with respect thereto, means for holding the member yieldably at one limit of its movement, said member being disposed to receive weight thereupon to move it against the action of the holding means, a cylinder having a closed end, a piston'slidably disposed withinv the cylinder, a piston-rod connected with the piston and slidably engaged in the endv of the piston, a pipe connected with the body portion and with the cylinder' between the closedend of the latter and the piston,

said cylinder, pipe and body portion being adapted for the reception of afluid therein, said member being arranged to force fluid from the body portion to the cylinder to move the piston in one direction when the member is moved against the action of the holding means, a pump-cylinder having inlet and outlet openings, valves for the openings, a discharge-pipe connected with the outlet-opening, a piston disposed within the pump, said piston being arranged for vertical movement, said valve being-located below the piston, connections between the last-named piston and the piston-rod for movement of said piston upwardly when the first-named piston and its piston-rod are moved by the fluid', and weights for the second-named piston.

In testimony whereof we aliix our signatures in presence of two witnesses.
